I have a problem when rainning elastic search

```
Caused by: java.lang.IllegalStateException: failed to obtain node locks, tried 
[[/usr/share/elasticsearch/data]] with lock id [0]; maybe these locations are not writable or 
multiple nodes were started without increasing [node.max_local_storage_nodes] (was [1])?
at org.elasticsearch.env.NodeEnvironment.<init>(NodeEnvironment.java:300) ~[elasticsearch- 
6.8.3.jar:6.8.3]
at org.elasticsearch.node.Node.<init>(Node.java:296) ~[elastic
```

Delete the file inside /usr/share/elasticsearch/data for each nodes and reboot  
Then restart the service again.
